Oil selection for Lehmans
Having owned two boats(GB 42 & Alaskan 46) with Lehmans, & sailed great lakes & east coast, I used single viscosity oil exclusively. Seem to remember conversation with Bob Smith's company and many others regarding oil, and the firm opinion of selection (as I remember) is that multi viscosity oil is not recommended since the oil is continually passed thru the oil cooler which is dropping oil temp to raw water temp. As this is counter to the multi viscosity oil formulation single viscosity oil is recommended. So there is my recollection, anyone else have comments?
